Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning, specifically the variant used by Rust.

[0.10.2] - 2018-02-18

Fixed

• Fix building of messages with custom fields for types that don't have a GstStructure

Added

• VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref(), which work with VideoFrameRefs instead of full VideoFrames
• Getters for the BaseSrc/Sink/Transform configured segment
• Document the gstreamer-player-1.0 dependency in the README.md

0.10.1 - 2018-01-03

Fixed

• Don't require &mut self for TagSetterExtManual::add()

Added

• A TagSetter example application
• Bindings for gst_video::convert_sample() and ::convert_sample_async()
• Bindings for gst_video::VideoRectangle
• Debug impl for Sample and ::with_buffer_list() constructor
• A borrowing version of VideoFrame: VideoFrameRef
• Bindings for GstVideoFilter

Changed

• Deprecated Sample::get_info() in favour of ::get_structure()
• Player has gst::Object as another parent class now

0.10.0 - 2017-12-22

Fixed

• Various clippy warnings
• Memory leak of the tag list in Toc::merge_tags()
• Property getters use Values of the correct type
• Event::get_structure(), Message::get_structure() and Query::get_structure() can return None for the structure
• Various other nullability fixes all over the API, changing functions to accept Option<> or returning Option<>, or only plain types
• Functions taking paths/filenames now actually take Paths instead of &strs
• Element::remove_pad() is not giving away a new reference to the pad anymore, which caused a memory leak of all pads ever removed
• Precision handling in ClockTime's Display impl
• Video/AudioInfo are only Send, not Sync

Added

• Various enums now also derive useful traits like Copy, Clone and Hash in addition to PartialEq, Eq and Debug
• TagList::merge() and insert() for combining tag lists
• EventType gained many useful functions to work with event types and a PartialOrd impl to check expected event order of event types where it matters
• MessageRef/EventRef/QueryRef implement ToOwned
• Bindings for Registry and PluginFeature
• Event::set_running_time_offset() for adjusting the offset while events pass through the pipeline
• Event/Message GroupIds and Seqnums now have a newtype wrapper around u32 instead of the plain value, making usage of them slightly more typesafe. Also add an "invalid" value for both, as exists in latest GStreamer now.
• FormattedValue, GenericFormattedValue and related types were implemented now, which allows more convenient and type-safe usage of formatted values (time, bytes, etc)
• Bindings for force-keyunit and still-frame events were added
• MappedBuffer/BufferMap now implement various other useful traits, including AsRef<[u8]>, AsMut, Deref, DerefMut, Debug, PartialEq and Eq
• Add VideoMultiviewFramePacking enum, and use it in Player
• Bindings for the GStreamer Net library, including PTP/NTP/network client clocks and the GStreamer NetClock provider for network synchronization of pipelines
• IteratorError implements std::error:Error
• Plugin::add_dependency() and ::add_dependency_simple() was added
• Rank and TypeFindProbability implement PartialOrd/Ord now
• Bindings for TypeFind, TypeFindFactory and the typefind helpers
• StreamCollection::iter() for iterating over all contained streams
• ErrorMessage type that can be used e.g. in a Result for passing an error message from somewhere to upper layers to then be posted on an element the same way gst_element_error!() would've done

Changed

• Sample::new(), TagList::add(), Structure::set() and similar functions take the values (ToSendValue impls) by reference instead of value. They were not consumed by the function before.
• The Debug impls of various types, including Event/Buffer/Message/Query/Structure were improved to print all the fields, similar to what GST_PTR_FORMAT would do in C
• Switched to lazy_static 1.0
• Gap event and Duration tag are using ClockTimes now, as well as various Player signals
• Segment is now based on a generic type FormattedSegment that can take any format (time, bytes, etc) or a GenericFormattedValue for more type-safety and convenience. Also functions for "casting" between a generic segment and a segment with a specific format exist on this now
• AppSrc and AppSink now have a builder for the callbacks, making it unnecessary to always provide all callbacks even if only one is actually needed
• Various functions that returned bool for errors, are now returning a Result
• Player configuration is now a custom type with more convenient API
• Player VideoInfo uses a Fraction instead of (u32,u32) for the framerate and pixel-aspect-ratio
• VideoFrame API has more consistent API between writable and read-only variants
• Buffer::copy_into() was added, and ::copy_region() now takes a BufferCopyFlags parameter instead of always using the default flags
• ChildProxy::set_child_property() takes a &ToValue now to follow the API of Object::set_property() and improve usability
• Proxy/GhostPad default pad functions use the correct specific pad type now instead of a generic Pad
• Bus::add_signal_watch_full() takes a Priority for the priority instead of u32
• Clock::(un)adjust_with_calibration() takes no clock parameter anymore

Removed

• FormatValue was removed in favour of GenericFormattedValue and the connected traits and specific format impls

0.9.1 - 2017-11-26

Fixed

• Export FlowError/FlowSuccess, ClockError/ClockSuccess, PadLinkError/PadLinkSuccess too

0.9.0 - 2017-11-26

Added

• Bindings for (outputting to) the GStreamer logging system
• Bindings for the GStreamer base library
• Bindings for all the Pad functions to override pad behaviour, and pad task functions
• Bindings for StaticCaps and StaticPadTemplate
• Bindings for deep-notify signal on Object
• Support for directly creating Error/Warning/Info Messages and posting them from an element with context information (file, line, module, etc.) similar to the C GST_ELEMENT_ERROR macro
• Support for setting custom fields in Messages/Events during construction
• Support for creating Buffers out of anything that is AsRef<[u8]> or AsMut<[u8]>
• Support for using the Read trait on Adapter
• Functions for getting all sink/src/all pads of an Element, and all children of a Bin
• Builder for Caps and Structures in addition to the existing functions
• AppSrc/AppSink implement BaseSrc/BaseSink and URIHandler
• Rust ports of the basic tutorials 1 to 8 from https://gstreamer.freedesktop.org/documentation/tutorials/
• "Getting started" and "Installation" sections to the README.md
• "dox" feature for generating documentation for all available configurations

Fixed

• StackTraceFlags are only available since 1.12
• Worked around macOS requiring a NSRunLoop running on the main thread in all examples and tutorials, to be able to show a window or anything else

Changed

• ClockTime is now a wrapper around Option<u64> to handle the CLOCK_TIME_NONE case better. This wrapper implements all the arithmetic and other traits as needed and ensures that no accidential calculations with CLOCK_TIME_NONE can happen

• "Values with format", like in Duration/Position/Convert queries or Seek events now return a FormatValue type. This contains the actual Format together with the value and does any required conversions. This also makes it harder to accidentially mix e.g. values in bytes and time

• PadProbeId does not implement Clone/Copy anymore

• Property notify watches return a custom type instead of ulong

• Error/Warning/Info Messages can only be created with specific kinds of glib::Error now. Using arbitrary ones does not work

• Iterator bindings were completely rewritten and provide the item type as a generic type parameter now, greatly simplifying its usage

• All glib::Values are now glib::SendValue instead, e.g. in Caps and Structures, as their content must be possible to send to different threads safely

• Message::get_src() can return None

• Allow None as Caps in AppSrc/AppSink

• Allow everything implementing Into<Option<&str>> to be used as a pad name

• Moved copy() from GstRc directly to MiniObject

• Success/Error enums (like FlowReturn, PadLinkReturn, StateChangeReturn) now implement an into_result() function that splits them into a Result with the good and bad cases. Also mark them as #[must_use] to make it harder to accidentially ignore errors.

• Error enums implement the Error trait

• Many examples use the failure crate for error handling now, cleaning up the error handling code quite a bit

• Lots of other code cleanup, compiler/clippy warning cleanup, etc.

0.8.2 - 2017-11-11

Fixed

• Implement StaticType of BufferRef instead of Buffer. Buffer aka GstRc already implements StaticType if BufferRef does, and without this it was not possible to use Buffers in GValues.
• Free memory of the appsink/appsrc callbacks with the correct type. It was crashing because of using the wrong type before.
• Fix documentation URLs in Cargo.toml.

Added

• Installation instructions and links to documentation for getting started to README.md.

0.8.1 - 2017-09-15

Added

• Implement Send+Sync for Query, Message and Event, and their corresponding Ref types.

Fixed

• Constructor for gst_player::Player now works properly with GStreamer 1.12 when passing a video renderer or signal dispatcher. There was a reference counting bug.
• Instead of returning &'static references from functions, return references with a generic, unbound lifetime instead. See https://github.com/rust-lang/rust/pull/42417#issue-233404573
• Various "unused external crate" warnings and clippy warnings everywhere.

Changed

• Remove Cargo.lock from GIT, it's not very useful for library crates.
• Run everything through latest rustfmt-nightly.
• Use while-let (instead of loop and if-let) and CLOCK_TIME_NONE (instead of u64::MAX) in the examples.

[0.8.0] - 2017-08-31

• Initial release of the autogenerated GStreamer bindings. Older versions (< 0.8.0) of the bindings can be found here. The API of the two is incompatible.
